I found this tonight and thought I would share. It is a miniature linear actuator 1.67 in long with an arm that has a little over 3/4 inch travel (20mm). The one with the 100/1 gear has about 7 pounds of force. You can get it with end travel limit switches built in and they all have internal potion feedback. Operating voltage in 6VDC and they sell for $65.00! A control board for precise position control is $40.00 or just use a $6.00 rocker switch for control. This is a lot cheaper than the Ray Allen units. Also the mounting looks easier than using an electric mirror drive.
Would this not be about perfect for elevator and aileron trim? There are larger more powerful units if you think you need them. (No, I am not affiliated with them). I'm working on a couture for my seat before I start using the carbon fiber. Bob Johnson Willamina, OR 971-645-9491 http://picasaweb.google.com/103552664644911775549/KR2SS#
